It is believed that Cavendish is called so because a man called Cafa used to own a pasture or 'edisc' there, and it therefore became known as Cafa's Edisc and eventually Cavendish.[citation needed] It was home to Sir John Cavendish, the ancestor of the Dukes of Devonshire who was involved in suppressing the Peasants' Revolt. Wat Tyler, the peasants' leader was arrested by William Walworth, the Mayor of London, for threatening King Richard II in 1381. As Tyler fought back Cavendish's son, also called John Cavendish, who was responsible for escorting the King, ran Tyler through with his sword, killing him.[1] As a result, John Cavendish tried to flee from the pursuing peasants, and he hung on to the handle of the door of St Mary's Church, Cavendish, to plead sanctuary.[2] A few days later, on 15 June 1381, the elder John Cavendish was seized at Bury St Edmunds and beheaded by a mob led by Jack Straw.[3] He is buried in Bury St Edmunds. St. Mary's Church had a bequest from Sir John, and its chancel was restored.[citation needed]
